Tourism & development: concepts and issues
2016
In this interesting book, Richard Sharpley and David Telfer edit 16 chapters that discuss the role of tourism as a facilitator of development for third-world. Though this classic work was already p...
Being lost: tourism, risk and vulnerability in the post-‘9/11’ entertainment industry
2012
This study explores the ways in which the post-‘9/11’ film industry employs tourism as a plot that re-creates mythical imageries of the ‘West’ in relation to a radical ‘other’. Reflecting on sociological and psychological concepts of ‘vulnerability’ and ‘risk’, the authors undertake a content analysis of four ‘horror’ or ‘terror’ films and reveal complex discourses linked to nationalist sentiment, political ideology, the power of expertise and public insecurity in the post-‘9/11’ USA. One interesting feature of the current horror-movie genre is the extent of violence and sadism exerted on Western tourists going abroad. Drawing on the image of the tourist as victim, the authors further discu…
Examining the Impact of eWOM-Triggered Customer-to-Customer Interactions on Travelers’ Repurchase and Social Media Engagement
2021
Electronic word-of-mouth (eWOM) communication on social media has revolutionized how travelers search for and share information and how they interact with one another digitally. This research examines the effects of eWOM-triggered customer-to-customer (C2C) interactions on travelers’ post-eWOM behaviors (i.e., repurchase and customer engagement) in a cross-cultural context. Drawing upon cognitive dissonance theory, a scenario-based experiment was conducted using a sample of 461 African tourists with recent intracontinental travel experience. Our findings suggest that a customer’s repurchase intention and engagement in social media C2C interactions are significantly influenced when their eW…
Un-rooted grafted cuttings for eggplant plug-transplant production and shipping: simulated transportation and healing requirements
2019
Vegetable grafting is one of the most effective eco-friendly techniques to overcome pests and soilborne diseases in modern cropping systems of fruiting vegetables. Due to the increased farmers’ preference for grafted seedlings of high quality and better performance, the use of vegetable grafted plants is rapidly spreading and expanding over the world and intensive researches on new commercial production systems are under way. However, in many areas of the world, due to the high cost of skilled manpower, the use of grafted plug plants is still limited causing a relatively slow development of the grafting nursery industry. The aim of this work was to evaluate a possible use of un-rooted graft…
Criminal networks analysis in missing data scenarios through graph distances.
2021
Data collected in criminal investigations may suffer from: (i) incompleteness, due to the covert nature of criminal organisations; (ii) incorrectness, caused by either unintentional data collection errors and intentional deception by criminals; (iii) inconsistency, when the same information is collected into law enforcement databases multiple times, or in different formats. In this paper we analyse nine real criminal networks of different nature (i.e., Mafia networks, criminal street gangs and terrorist organizations) in order to quantify the impact of incomplete data and to determine which network type is most affected by it. The networks are firstly pruned following two specific methods: …
Modeling crowd dynamics through coarse-grained data analysis
2018
International audience; Understanding and predicting the collective behaviour of crowds is essential to improve the efficiency of pedestrian flows in urban areas and minimize the risks of accidents at mass events. We advocate for the development of crowd traffic management systems, whereby observations of crowds can be coupled to fast and reliable models to produce rapid predictions of the crowd movement and eventually help crowd managers choose between tailored optimization strategies. Here, we propose a Bi-directional Macroscopic (BM) model as the core of such a system. Its key input is the fundamental diagram for bi-directional flows, i.e. the relation between the pedestrian fluxes and d…
Data Acquisition System for the Characterization of Biomechanical and Ergonomic Thresholds in Driving Vehicles

Directive (EU) 2015/653 on driving licenses has involved the modification of different codes that must appear on driver&rsquo
Integration of foreign trade and maritime transport statistics in Spain
2010
This article aims to contribute to improving maritime trade data by analysing the possibility of integrating in a single enlarged databank two different databases: the Spanish foreign trade and maritime transport datasets. The methodology adopted consisted of studying the primary sources providing data compiled in the foreign trade and maritime traffic databases, analysing the electronic processes used by informants and data collectors and examining the linkages between the different electronic messages involved. Once the links between the trade and sea transport documents and electronic messages were found, a solution for integrating both databases was envisaged. The main outcome is a new …
Geo‐referencing naturalistic driving data using a novel method based on vehicle speed
2013
Naturalistic driving is an experimentation model that allows us to recognise the driving modes observing the driver's behaviour at the wheel of a set of people in natural conditions during long periods of observation. This research methodology aims at increasing the representativeness of the data collected in opposition to data stemming from highly controlled laboratory experiments. However, naturalistic driving research designs produce large volumes of data that are difficult to handle. Thus, it is very important to work with suitable methods for representing and interpreting data, allowing us to observe the variability of the results. The aim of this study is to implement a new methodolog…
A GIS-based method for evaluating the walkability of a pedestrian environment and prioritised investments
2020
Abstract Despite the large investments made in the construction and modernisation of railway infrastructure, poor quality pedestrian routes may discourage users from using public transport. In fact, very little attention is generally paid to pedestrian mobility. Therefore, a method for evaluating the quality of pedestrian paths and the accessibility to railway stations has been developed. This method considers the main factors influencing the walkability of an urban area and makes it possible to establish the priorities for intervention, i.e. to identify the arcs of a pedestrian network that require prioritised action. The methodology is a decision support tool that can be used by policymak…
